Wisconsin Gov. Scott Walker is planning to announce his candidacy for the Republican presidential nomination one week from today.

The event is planned to take place at the Waukesha County Expo Center in Waukesha, WI. It will begin 4:45 p.m. with the introduction set to begin at 5:15 p.m. Doors open at 3 p.m.

Walker has been the early favorite amongst polls since his speech at the Iowa Freedom Summit in Des Moines in January. His numbers have fallen off as the field has grown, and as voters learn more about Walker and each of the other candidates.

In the run-up to the announcement, the Walker campaign has been unveiling a portion of the official logo each day since early last week.
